These are names that are already registered, but you can request a domain registration under them. The full list of the second level subdomains under .hu is this:
| co.hu | 2000.hu | erotika.hu | jogasz.hu | sex.hu | video.hu |
| info.hu | agrar.hu | film.hu | konyvelo.hu | shop.hu | |
| org.hu | bolt.hu | forum.hu | lakas.hu | suli.hu | |
| priv.hu | casino.hu | games.hu | media.hu | szex.hu | |
| sport.hu | city.hu | hotel.hu | news.hu | tozsde.hu | |
| tm.hu* | erotica.hu | ingatlan.hu | reklam.hu | utazas.hu |
*Only domain names that are the trademark of the applicant can be chosen under tm.hu.
So, if the name of my company is for example Accountantcompany Ltd., but accountantcompany.hu is already registered, then I can choose accountantcompany.konyvelo.hu or accountantcompany.co.hu.
The name of a second level public domain usually shows what types of companies and organizations should register a domain name under them, but there is no restriction except for the above mentioned tm.hu.
